I’m so sorry to hear that your child is suffering. I know how awful that can be. 🙁 If your child is experiencing symptoms of low acetylcholine release (fatigue, constipation, dry eyes, fast heart rate, etc), I would try 1-2 capsules first thing in the morning on an empty stomach. The chance of getting too much is very slim, but should that happen, your child’s eyes may be very moist, resting heart rate will slow, etc. Please keep us posted, and know that you are superwoman when you can get your child to take necessary pills! lol This is what allowed our young son to start to absorb nutrients again, recover from POTS and fatigue, and heal from severe osteoporosis.
